Will i damage small solar panels on a car battery? Answered
I've got a couple tiny solar panels and i wanted to have them charge a car battery, The panels in series put out 18v at 50ma but the leads are just those tabs they spot weld to batteries. Is it possible to fry the solar panel or leads?
I am not sure about amperage of the battery. It's similar to one i bought a long time ago with 650 Cold cranking amps(not sure how that translates to total amperage but i'm guessing that is how much you can safely draw from it at one time)
i understand that it wouldn't be proper to attach 18 volts to a 12 volt car battery, it charges at around 15 volts like most car batteries.
I understand that 50ma will take an extremely long time to charge something like a car battery.
But in a hypothetical emergency situation, would this work temporarily without destroying the solar panels.
